SAMUEL V. KENNEDY AND CHARLES A. ANDERSON, OF MINNEAPOLIS, MIN- NESOTA, ASSIGNORS TO THE MINNEAPOLIS HARVESTER WVORKS, OF

SAME PLACE.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 385,059, dated June 26. 1888.

Application filed September 8, 1887. Serial No. 249,062. (No model.)

To all whom it may] concern:

Be it k nown that we, SAMUEL V. KENNEDY and CHARLES A. ANDERSON, of Minneapolis, Minnesota, have invented certain Improvements inGrain-Binders, of which the following is a specification.

This invention relates to self-binding harvesters of the class in which the packers re main at rest during the binding operation and [O resume their labor at the completion thereof;

and it consists of certain mechanism for producing this result in an especially simple and effective manner, the characteristic feature of which is asingle stop-lever or stop-dog, which is by its vibration in one direction releases the binder and stops the packer and then by its vibration in the opposite direction releases the packer and stops the binder.

The invention also embraces an improved construction of the binder-frame, whereby a more stable support is provided for the packershaft and the intermediate gearing, which communicates motion to the binder.

The accompanying drawings are as follows,

viz: Figurel is an elevation of the binder,

looking from the grain side; Fig. 2, an elevation from the front with the binder at rest and the packers in operation; Fig. 3, a similar View with the packers at rest and the binder 0 in operation,the packers and some otherparts being omitted to more clearly show the other devices; Figs. 4 and 5, different views of the stop dog and trip-shaft; Fig. 6, a sectional view of the intermediate gears, 4; and 4, on

5 the line 00 av of Fig. 3. Fig. 7 shows the packer-shaft 8, the main driving hollow shaft 9, the bindendriving pinion 5, and packerdriving head 10. In this view the parts are separated from each other to more clearly show their construction, they being shown in proper relation in Fig. 1. Figs. 8, 9, and 10 are sectional views taken on the line y y of Fig. 7. Figs. 11 and 12 are details on a reduced scale, showing the binder-frame construction.

. 5 The binder-frame 1 is provided with the laterally-projecting.flange a, in which are the usual seats, I) I), for the studs, upon which the intermediate gears are journaled, and with another laterally-projecting flange, c, at a sufiicient distance in advance of and parallel with the flange a to admit the intermediate gears,

4. 4, between it and the flange (t. The rear end of the stud f is seated in the flange a, and its front end is seated in the flange 0, thus making the bearing for the gears 43 and at very firm and substantial. The flange 0, projecting downward from the lower horizontal member of the binder-frame, affords the rear bearing for the packershaft. The flange 0 also furnishes for the packer shaft a bearing, 9, outside of the gearing, &c., thus giving the packer'shaft and principal driving mechanism an especially stable support.

2 is the main binder gear; 3, an intermediate gear for communicating motion to the 6 main gear 2. 4t and 4; are intermediate gears mounted upon the same axle. The gear at engages with the gear 3, to drive the same, and has pivoted to its inner side ie, the side next to the gear 4:the binder-driving dog 6, which dog is provided, as shown, with a lateral arm projecting between the spokes of the gear to which the dog 6 is pivoted, and across the plane in which the stop-dog 14 vibrates. The collision of the driving-dog 6 with the stop-dog 14 serves to stop the binder. The gear 4 engages with and receives motion from the main driving-pinion 5, and is provided, as shown, with the rollers 7 7 7, adapted to act against the dog 6, and therebyto impart rotation to the gear 4 and thus drive the binder. The driving-pinion 5 runs loosely upon the packer-shaft 8, and is driven by being clutched with the continuously-running hollow driving-shaft 9, as shown.

The clutching mechanism consists of the lips E E, projecting laterally from the side of the pinion 5, and embracing the sides of the cross-head E, formed upon the end of the hol- 0 low driving-shaft 9. The hollow drivingshaft 9 is itself driven by means of the usual sprocket'wheel, A, and chain A, the sprocketwheel A being held in place during the adjusting movements of the binder by means of the ordinary yoke attached to the frame of the harvester. The bifurcated arms B B of the yoke bear respectively upon the opposite ends of the hub A of the sprocket-wheel A.

To provide for the operation of thepackers, 10o

the packershaft 8 has affixed to its forward end a head, to which is pivoted a rocking dog, 11, having upon its rear side a projection which constitutes the pawl 12.

A spring, h, carried upon the head 10, and acting upon the longer end of the rocking-dog 11, as shown in Fig. 10, tends to swing the free end of the pawl 12 outward into the concentric path of movement of the pushers 13 13, affixed to the front side of the pinion 5. As will be seen on reference to Figs. 8 and 9, the pushers 13 13 are simply flanges in the form of concentric arcs projecting laterally from the face of the pinion 5. The ends of thesefianges, which are at right angles with the face of the pinion 5, are slightly concave, in order that they may be concentric with the axis ofthe pawl 12. a By the collision of one of the pushers 13 with the free end of the pawl 12, as shown in Fig. 9, the. rotating motion of the pinion 5 is imparted to the head 10, and thus to the packer-shaft 8.

A stop-dog, 14, is rigidly secured to the forward end of the trip-shaft 15, and has at its free end a rearwardlyturned finger,7c,as shown in Fig. 4. When the stop-dog 14 is swung downward,the finger 7c is carried into position to engage one or the other of the ends of the rocking dog 11,and to thereby swing the pawl 12 inward out of the path of movement of the pushers 13 13, as shown in Fig. 8,whereby rotatory motion ceases to be imparted to the packer-shaft 8.

During the latter part of the binding operation the cam on the main gear rocks downward the upper end of the lever 16, and by means of the rod 17, connecting the lower end of the lever 16 with the stop-dog 14, pulls the latter upward, carrying its finger it into position to engage the laterallyprojecting arm of the dog 6, and thereby stop the imparting of motion to the binder. As in the well-known Appleby binder, the upper end of the lever 16, by acting upon the usual notch in the maingear cam, serves to give a slight forward impulse to the main gear, and then to hold it positively in position during the time while the packers are operating.

The lower portion of the rod 17 is offset to form the shoulder l, and, having been loosely inserted through a hole in the stop-dog 14, is provided with the expanding spiral spring 18, which exerts its thrust in one direction against the under side of the stop-dog, and in the opposite direction against the adjusting-nut 19, screwed onto the threaded lower portion of the rod 17. The tripshaft 15 has affixed to its rear end the crank-arm 20, and has loosely sleeved upon it, next adjoining the crank-arm 20, a yoke, 21, to which the lower ends of the packers are connected by the links 25 25, re spectively. The yoke 21. is provided with a laterally projecting lip, 22, through which there is inserted a set-screw, 23, in position to bear against the crank-arm 20. During the operation of packing the grain the yoke 21 is forced to swing outward in the direction of the arrow m, (shown in .Fig. 2,) by reason of its connection, by means of the links 25,with the lower ends'of the packers and the collision of the set-screw 23 with the crank-arm 20. The outward swing of the cranlcarm 20 rocks the tripshaft 15 in its bearings. The stop-dog 14, being rigidly attached to the trip-shaft 15, is thus swung downward a sufficient distance to disengage its free end from the driving-dog 6.

The yoke 21 is provided with a lateral projection or boss, 26, which plays within the notch 27, formed in the binder-frame. The Width of this notch determines the range of swinging movement which the yoke 21 is permitted to have. little more than sufficient to permit the free end of the stop-dog 14 to be swung downward out of engagement with the driving-dog 6,and to thus trip the binder into gear; but as this limited range of movement is not sufficient to carry the stop-dog downward within reach of the rocking-dog 11 of the packerclutching mechanism, the crank'arm 20 is left free to rock away from the end of the set-screw 23, as shown in Fig. 3. The necessary additional movement of the stop-dog 14 is given to it the instant the binder-gear starts, by the expansion of the spring a, which rocks the lever 16 upward, and by means of the rod 17 pushes downward the stop-dog 14, and thereby rocks the shaft 15 and carries the crank-arm 20 away from the set-screw 23. During the latter portion of the binding operation the lever 16 is rocked downward by the cam on the main binder-gear, and the rod 17 being thus pulled upward the spring 18 is compressed until its thrust upon the under side of the stop-dog 14 is strong enough to disengage the stop-dog 14 from the packer-clutching mechanism andcarry it upward into the position in which it engages the driving-dog 6. By this upward movement of the stop-dog 14 the arm 20 is carried intocollision with the set-screw 23, and the yoke 21 is consequently rocked backward until the projection 26 brings up against the side of the notch 27, as shown in Fig. 2. It will therefore be seen that the setscrew 23 in the yoke 21 affords a means of varying the range of upward movement of the stop-dog 14. By screwing in the set-screw 23 the arm 20 will be sooner brought into collision with it during the upward movement of the stop-dog 14, and the upward movement of the stop-dog 14 will be therefore sooner arrested by the collision of the projection 26 with the side of the notch 27, and, on the other hand, by unscrewing or turning out the set-screw 23 the stop-dog 14 will be permitted to move farther upward be fore its motion is arrested by the collision of the arm 20 with the end of the set-screw 23 and the bringing up of the projection 26 on the side of the notch 27. There is thus afforded a means of varying the depth of engagement of the stop-dog 14 with the driving-dog 6, and hence of governing the extent of downward This range of movement is a movement whiehmust be giveuto the stopdog' 14 to disengage it from the driving-dog 6, and to thus permit the driving-dog 6 to start the binder into operation. The downward movement of the stop-dog 14 is at this time resisted by the spring 18, and hence the disengagement of the stop-dog 14 from thedriving'dog 6 will not be effected until there has been such an accumulation of grain in the gavel-receptacle that the resistance opposed to the stroke of the packers is great enough to overbalance the resistance which the spring 18 opposes to the downward movement of the stop-dog 14. It will therefore be seen that while the adjusting-nut 19 affords a means of regulating the tension of the spring 18 the provision of the set'screw 23 in the yoke 21 affords a means of increasing or decreasing the extent to which the spring 18 must be compressed in the act of tripping the binder into gear.

Just at the conclusion of the binding operation, as represented in Fig. 2, the laterallyprojecting arm of the binder-driving dog 6 is carried against the lip k of the stop-dog 1i, and the dog 6 is thereby rocked out of the path of the driving-rollers 7 on the gear 4Zwhich thereafter revolves without impart-ing its rotation to the gear at, and hence leaves the binder at rest. In the meantime the lip k of the stopdog 14 has been swung upward out of engage ment with the rockingdog 11, and under the influence of the spring h the pawl 12 has been rocked outward into the path of the pushers 13 13, so that as soon as either of the pushers engages the pawl 12 the rotatory motion of the continuously-rotating pi nion 5 will be imparted to the packer-shalt 8, as has been described, thus setting the packers at work. When sufficient grain has been accumulated for a bundle, the trip-shaft 15 will be rocked in its bearings by reason of its connection with the packers through the links 25 and the yoke 21. The set-screw 23 of the yoke 21, pushing against the crank-arm 20, rocks the trip-shaft and the arm 20 in the direction indicated by the arrow min Fig. 2. The stop'dog 14, being secured to the trip-shaft, is thereby rocked downward, thus releasing the binder-driving dog 6, which is then thrown by its spring D, as shown in Fig. 3, into position to be engaged by some one of the rollers 7 7 7 on the gear a Such engagement imparts rotation to the gear 4, as has been described, and again starts the binder into operation. WVhen the bi ndcr-gear 2 commences its movement, the upper end of thelever 16 is released from its notch in the binder-cam and thrust upward by the expandthe pushers 13 13 on the pinion 5, as shown and described. The rockingdog 11 in rocking back upon its pivot uncovers one of the notches p p in the periphery of the packer-driving head 10, into which the lip 7c of the stop-dog letis forced, as shown in Fig. 3, and thus locks the packers.

As has been explained, provision for perdriving dog 6 to hold the latter disengaged from either of the driving-rollers 7 7 7 is adjusted by the setscrew 23 bearing against the crank-arm 20 of the trip shaft 15, to which the stop-dog 14. is attached. It will thus be seen that the drive-dog 6, pivoted to the gear 4, and the rollers 7 7 7, carried upon the gear 4 constitute the clutching mechanism for driv ing the binder, and that the rocking-dog 11, carrying the pawl 12, pivoted to the packershaft head 10, and the pushers 13 13, affixed to the side of the continuously-rotating pinion 5, constitute the clutching mechanism for driving the packers,and that the arm of the binderdriving dog 6 and the ends of the rocking-dog 11, carrying the packer-driving pawl 12, are arrangedin the vertical plane in. which the stop-dog 14- vibrates, and that the organization is such that the stop-dog 14 arrives at the end of its upward excursion in time to intercept the arm of the binder-driving dog 6, and by its collision therewith rocks the dog 6 out of the path of the rollers 7 7 7, and thus disconnects the clutching mechanism for driving the binder, and similarly arrives at the end of its downward excursion'in time to intercept one of the ends of the rocking-dog 11, by engaging which it rocks the pawl 12 out of the path of the pushers 13 13, and thus disconnects the clutching mechanism for driving the packers.

Vhat is claimed as the invention is- 1. In a grain-binder wherein the binder proper and the packers work and rest alternately, clutching mechanism to drive the binder, and clutching mechanism to drive the packers, in combination with a single stopdog in the form of an arm pivoted at one end and swinging in the plane in which the said clutching mechanisms are arranged for acting alternately with the clutching mechanisms of the binder and packers to stop and hold one at rest while the other is in operation, substantially as set forth.
